SIGNAL-LANTERN.

SPECIFICATION forming part of Letters Patent No. 283,633, dated August 21, 1883.

Application filed June 20, 1883. (No model.)

county of Philadelphia, State of Pennsylvania,

have invented a new and useful Improvement in Signal-Lanterns, which improvement is fully set forth in the following specification and ac companying drawings, in which-- Figure l is a vertical section of a signal-lam tern embodying our invention. Fig. 2 is a side elevation of another form thereof. Fig. 3 is a view of a modification.

Similar letters of reference indicate correspending parts in the several figures.

'oversa when the same is in n ri ht or 0 4 1 Our invention consists of a signal-lantern having a body of different colors, whereby, by

' proper rotation of the same, either color may be displayed.

Referring to the drawings, A represents the body of a lantern, the same having two transparent globes, A, of different colors, located one above the other, and united by an intermediate rim, A.

B represents gudgeons projecting from the rim A, and forming connections for the pivoted bail or handle 0, and constituting a horizontal axis for the body A.

On the inner face of the rim A, at opposite 0 places, are horizontal grooves c a, in which are loosely fitted the gudgeons of a swinging or gravitating lamp, D, said lamp being so weighted or centered that it always stands upright or is self-righting, and its flame illuminates the upper globe, A, without a similar effect on the lower globe.

Attached to the base-rims, or to the guards of both globes A, are catches E, which are adapted to engage with the bail G, or vice 'erative position, as shown in Fig. 1, whereby the bail is rigidly held. l/Vhen the color of the signal is to bechanged, the bail is released from the catches E and the body turned on the gudgeons, so that the two globes change positions, the desirable color thus being above and illuminated, and the lower color remaining nnilluminated. The bail is then locked or secured, andthe lantern may be carried thereby and operated as desired. In this rotary motion of the body of the lantern the lamp remains suspended in its normal position, the rim of the body turning around the gudgeons or axis of the lamp without materially disturbing the same.

If desired, the ends of the bail may be con neoted with the sides of the lamp and constitute the axis of the body of the lantern, the rim being mounted on said ends of the bail, as shown in Fig. 3, without, however, producing difierent results from those stated.

In orderto light the lamp, or provide access thereto, the rim is formed of two parts, which may be separated, so that the upper globe may be readily removed, thus nnoovering the top of the lamp. This provision is also availed of for uncovering the gudgeons of the lamp, so

that the latter may be removed from the rim.

the base-rim of each globe a flag-staff, F, the

two staffs carrying flags of different color or characters. The bail, as such, is dispensed with, and in lieu thereof the gudgeons of the body of the lantern, are supported on a yoke,

G, which forms a stand, and receives between' it the lower flag and staff not in service, the same being concealed by a sheath, H, the outer 'endwhereof drops into an opening in the base of the yoke G, whereby the body of the him tern is locked and held in position, and the I loss of the sheath is prevented.

It is evident that when the sheath is raised it is disengaged from the yoke, and the body may be rotated, so as to bring the desired color of the same to the top and display it by the illumination thereof. This provision of the rotation of the body also permits a differentcolored flag to be displayed at top, the lower flag being sheathed; but both flags may be sheathed when neither of them is required.

The yoke or stand G is secured to the proper part of the locomotive in any desirable manner.

Having thus described our invention, what we claim as new, anddesire to secure by Letters Patent, is I 1. A signal -lantern' having a transparent body formed of two parts or globes of differ ent colors mounted on a horizontal axis, and a lamptherein occupying'a position-intermediate of said parts, whereby when the globes are rotated upon their axis either color may be displayed by illumination with out similarly displaying the other, substantially as and for the purpose set forth.

2. A signal-lantern having a transparent body formed of two parts or globes of differ cut colors, a connecting-rim forthe-parts of said body, a swinging lamp within the body,
